Abstract
The utility model discloses a double-groove double-driving wheel drawing welding gun which is an improved device for a welding gun. The rotation of a wire feed wheel with a groove is driven by a motor arranged in a handle, and the wire feed wheel drives a wire press wheel with a groove to rotate together through a gear wheel. An inverse top type adjustable screw bolt stored at the inner side of an inner reed applies some force to a crank arm through a spring to control the wire press wheel to drive the advance of welding wires. The utility model has the advantages of novel structure, long service life, safety, unease of striking fire and stable wire feeding.
Description
The utility model belongs to the modifying device of electromechanical equipment welding gun.
Common carbon dioxide welding machine all is made up of power supply, wire drawing welding gun and air supply system.The power supply architecture of welding machine manufacturer is basic identical at present, stable performance, main crux is that the structure of wire drawing welding gun is outmoded, technology is coarse, make wire feed stable inadequately, directly influenced the complete machine performance, their work principle are to make driving force with the micromachine that is contained in the handgrip, pass through worm and wormwheel, drive wire feed rolls, the silk pressing wheel is sent welding wire, in order to increase the frictional force between wire feed rolls and the welding wire, the outer rim of wire feed rolls is rolled on straight flower, the silk pressing wheel replaces with little bearing, make the thrust change of spring and thrust is passed to bearing from connecting lever by adjusting bolt, thereby make welding wire compress (see figure 3), make welding wire produce sawtooth because flower is arranged above the wire feed rolls, sawtooth can wear and tear ignition tip, reduces service life.And the annular knurl on wire feed rolls surface, wearing and tearing also can reduce frictional force along with increasing service time, and flower contacts with the point of welding wire and also can often skid, and for increasing frictional force, just have to increase thrust, otherwise can increase the kinetic equation loss of motor again, makes the wire feed instability.
It is stable that the novel purpose of this use provides a kind of wire feed, the welding gun wire feeder of long service life.
A kind ofly be loaded on rotating in the welding gun handgrip by driven by motor wire feed rolls (1), and drive silk pressing wheel (2) is synchronized with the movement, force in thrust on connecting lever (3) the increase and decrease silk pressing wheel (2) by adjusting bolt (5) by spring (4), drive two wire feeders that increase pair driving wheel wire drawing welding guns that welding wire (6) advances.It is characterized in that wire feed rolls compresses employing back punching type compressing structure, wire feed rolls is the gear with middle trough of belt of identical modulus with the silk pressing wheel.Its groove can be V-type or semicircle, and it can obtain bigger extruding force with less normal pressure.Frictional force between wheel and welding wire is strengthened, and that gear structure can make a kind of power become is double dynamical, increases the wire feed dynamics, finally make wire feed stable, save power.And back punching type spring compression structure can make hold-down bolt, is hidden in spring inner, has avoided outside old-fashioned welding gun hold-down bolt is exposed to, and the disadvantage of sparking often takes place, and the assurance welding gun is not fragile.
Advantage of the present utility model is: wire feed is stable, welding gun long service life, novel structure, safe and reliable.
Accompanying drawing 1 is the structure chart of the wire feeder of double flute driving wheel wire drawing welding gun.Two wire feed rolls of this rifle of Fig. 2 and welding wire contact condition figure.Fig. 3 is the structure chart of the wire feeder of old-fashioned welding gun.Fig. 4 is that the wire feed rolls of old-fashioned welding gun is taken turns and welding wire contact condition figure with silk pressing.Wherein: the 1-wire feed rolls, 2-silk pressing wheel, the 3-connecting lever, the 4-spring, 5-adjusts bolt, 6-welding wire.
Claims (3)
1, a kind of be loaded in the welding gun handgrip by driven by motor wire feed rolls (1), and drive silk pressing wheel (2) rotates synchronously, force in connecting lever (3) increase and decrease silk pressing by spring (4) and take turns thrust on (2) by adjusting bolt (5), the wire feeder of the two driving wheel wire drawing welding guns of the double flute that drive welding wire (6) advances, it is characterized in that wire feed rolls compresses employing back punching type compressing structure, wire feed rolls is the gear with identical modulus of middle trough of belt with the silk pressing wheel.
2, the wire feeder of the two driving wheel wire drawing welding guns of double flute according to claim 1 is characterized in that groove is the V-type cross section.
3, the wire feeder of the two driving wheel wire drawing welding guns of double flute according to claim 1 is characterized in that groove is semi-circular cross section.
